TORCH 0R BURNER.

Specification of Letters Patent.

Patented Apr. 2'7, 1920.

To all whom it may concern:

Be it known that we, BENJIMAN F. HARDT and SAMUEL T. TAYLOR, citizens of the United States, residing at San Saba, in the county of San Saba and State of Texas, have invented certain new and useful Improvements in Torches or Burners, of which the following is a specification.

This invention relates to an improved torch or burner andhas as its primary object to provide a, device of this character which may be readily carried about and operated with ease and facility for burning or searing obnoxious growths or other vegetation.

The invention has as a further object to provide a device of this character employing a liquid fuel tank and wherein the tank will be equipped with a pump so that, as required, air pressure in the tank may be maintained for accordingly maintaining a proper flow of fuel at the jet or nozzle of the burner.

The invention has as a further object to provide a construction wherein the fuel tank will be equipped with an .air gage so that the operator may always be properly appraised as to the air pressure within the tank.

And the invention has as a still further object to provide a construction wherein the burner of the device may not only be rotated in a vertical plane, but may also'be swung in a horizontal plane so that the burner may be readily manipulated to direct the flame therefrom in the practical use of the device.

Other and incidental objects will appear hereinafter: In the drawings Figure 1 is a side elevation of our improved device showing the outer burner carrying section of the fuel pipe swung to inactive position,

Fig. 2 isa similar view showing the outer section of the pipe extended,

Fig. 3 is a sectional view on an enlarged scale showing the swivel coupling in the vertical portion of the fuel pipe of the burner, l

Fig. 4.1is a view similar to Fig. 3 showing the swivel coupling in the outer horizontal section of the fuel pipe of the burner, and

Fig. 5 is a fragmentary sectional view on an enlarged scale show ng the er in which the air pump is connected with the fuel tank and particularly illustrating the valve of the pump.

In carrying the invention into effect we employ a preferably cylindrical sheet metal fuel tank 10 closed at its ends by heads 11 and 12 respectively. These heads may be constructed of brass or other approved material. Connected with the tank is a suspension strap 13 by which the device may be carried about by the operator. Formed in the head 12 is a suitable filling opening which is normally sealed by a plug 14, the tank being designed to contain kerosene or other approved liquid fuel.

Extending from the tank at its outer side is a pump base 15 provided with an annular flange 16 and with an outwardly raised annular valve seat 17. Detachably connected with the base is a pump barrel 18 connected adjacent its outer end with the tank by a keeper 19 removably receiving the barrel. At'its outer end the barrel is closed by a head 20 and mounted to reciprocate within the barrel is a piston 21 from which extends a rod 22 slidably received through the head. At its outer end this piston rod is equipped with a suitable handle 23 and detachably engaging over one end of the handle is a keeper strap 24; which is appropriately secured to the tank 10 and is designed to normally maintain the piston at the limit of its inward movement within the barrel. Threaded into the flange 16 of the base 15 is a reduced valve casing 25 provided with a lateral branch 26 threaded through the wall of the tank. Mounted to reciprocate within the valve cas- .ing is a hollow valve 27 in which is mounted a packing 28 of cork or other. approved material adapted to engage the seat 17 Normally holding this packing in contact with the seat is a spring 29 bearing between the valve and a plug 30 closing the casing 25 at its outer end. As will be seen, this plug may be removed when the valve may be readily displaced from the casing. This construction provides an arrangement whereby the valve and packing 28 may, when found necessary, be easily renewed. As will be readily understood, the strap 24 may be released, when the handle 23 of the pump piston may be grasped and the pump operated for forcing air into the tank,- the valve 27 acting to check back-flow of air to the pump barrel. Threaded through the head 12 of the tank is a pressure gage 31. This pressure gage may be of any approved type and is designed to indicate the air pressure in the tank. Consequently, the operator may, whenever necessary, operate the air pump to maintain a desired air pressure within the tank, it always being possible to obtain a reading of such pressure by consulting the gage 31. a

Leading from the head 12 of the tank at the lower side of said tank is a fuel pipe. This pipe is composed of an inner horizontal section 32 connected with said head, a vertical section 33 extending upwardly from the section 32, and an outer horizontal section 34 connected with the section 33 and lying substantially parallel to the inner horizontal section. Interposed in the section 32 is a shut off valve 35 of approved type. Interposed between the sections 32 and 33 is a swivel coupling shown in detail in Fig. 3 of the drawings. This coupling comprises a pipe section 36 threaded at its lower end into an elbow connecting the section 33 of the fuel pipe with the section 32. Formed on the section 36 of said coupling is an annular shoulder 37 above which the pipe section is provided with flat wrench receiving faces. At its upper end, said pipe section is formed with a reduced nipple 38 and surrounding this nip le is an approved packing 39. Rotatably fitting over the up per end portion'of the pipe section is a sleeve 40, the passage through which is reduced adjacent the upper end of said'sleeve to snugly receive the nipple 38 and to define a shoulder abutting said packing. At its lower end the sleeve is threaded into a coupling nut 41 coacting with the shoulder 37 and rotatably connecti'ngthe sleeve with the pipe section 36. At one side, this nut is provided with a radial thumb screw 42 impinging against the sleeve for locking the sleeve and nut together. Threaded into the upper end of the sleeve 40 is the section 33 of the fuel pipe. 7

Interposed between the sections 33 and 34 of the fuel pipe is a swivel coupling shown in detail in Fig. 4 of the drawings. This coupling includes a pipe section 43 similar to the pipe section 36 of the coupling previously described. At one end, the pipe section 43 is threaded into an elbow connecting said pipe section with the pipe section 33. The pipe section 43 is formed with an annularshoulder 44 and beyond this shoulder with fiat wrench receiving faces while at its outer end the pipe section terminates in a reduced nipple 45. Surrounding this nipple is an approved packing 46. Rotatably fitting over the outer end portion of the pipe section is a sleeve 47, the passage through which isreduced to snugly receive the nipnited for heating the coil.

ple 45 and to provide a shoulder abutting said packing. At its inner end the sleeve is threaded into a coupling nut 48 coacting with the shoulder 44 and rotatably connecting the sleeve with the pipe section 43. At one side this nut is equipped with a radial thumb screw 49 impinging against the sleeve and locking the sleeve and nut together. Threaded upon the outer end of the sleeve is a valve casing 50 provided with an intermediate web 51 and reciprocable within the casing is a check valve 52 adapted to seat in closed'position against the outer end of the sleeve. At one side this valve is provided with a wing slidably received within the passage of the sleeve while, at its opposite side, the valve is provided with a similar wing slidably received through the web 51 of the casing. These wings will thus center and guide the valve in its movement. The section 34 of the fuel pipe is threaded into the outer end of the valve casing 50 and mounted upon this section is a hand grip 53. This grip is adjustable longitudinally upon the pipe section 34 and held at adjustment by a thumb screw 54.

Connected with the outer end of the section 34 of the fuel pipe is a burner. This burner includes a volute coil 55 having its 9 larger end presented downwardly and the pipe of which is extended from 'the bottom end ofthe coil laterally and is suitably connected with the outer end of the section 34 of the fuel pipe, it being observed in this connection that the coil is supported to incline rearwardly. At the upper smaller end of the coil, the pipe thereofis extended upwardly and'is equipped with a" suitable jet or nozzle 56 having its discharge 0 ening intersected by the axis of the coil. emovably fitted over the coil is a conical casing 57. This casing may be formed of sheet metal and snugly surrounds the coil. In operating the burner, liquid fuel is first allowed to flow over the coil and is then ig- Liquid fuel subsequently flowing through the coil will then be vaporized when the fuel vapors may be ignited at the nozzle 56 and since the flame from the nozzle will be confined by the casing 57 to pass within the coil, the coil will always be effectually heated. Furthermore, owing to the conical form of the coil, the flame passing therethrough will be allowed to spread toward the. lower end" portion of the coil. V V

In use, the tank 10 is first filled with a suitable quantity of liquid fuel when the air pump isoperated to obtain the desired air pressure within the tank. The burner is then lighted as previously described when the burner may be manipulated to direct the flame therefrom as desired. In this connection particular attention is directed to the highly practical advantages attained by the use of the two coupling sleeves employed in the fuel pipe. As will be clear in view of the preceding description, the coupling associated with the section 33 of said pipe will support this section to turn freely so that the outer section 34 of the pipe may consequently be readily swung in a horizontal plane upon said coupling and the burner thus freely directed accordingly. In Fig. 2, I have shown the outer section 34 of the fuel pipe swung to project forwardly from the tank 10 to support the burner in ac tive position, it being understood, of course, that the burner is first thus swung away from the tank before being ignited. Furthermore, as will also be clear in view of the preceding description, the coupling at the inner end of the section 3& of the fuel pipe will support this section of the pipe to freely turn in a vertical plane. Consequently, the burner may be readily rotated for further directing the flame therefrom as desired. It will, therefore, be seen that the two couplings provide for such movement of the burner that the burner may, in the practical use of the device, be advantageously manipulated.

Having thus described the invention, what is claimed as new is:

A burner of the class described including a horizontally arranged tank, a horizontal pipe extending longitudinally from one end of said tank adjacent its bottom, a vertical pipe carried by the outer end of said horizontal pipe in spaced relation to the adjacent end of the tank, a second horizontal pipe carried by the upper end of said vertical pipe and arranged in spaced relation to said horizontal tank, a swivel member interposed in said vertical pipe to permit said second named horizontal pipe to be swung about a vertical axis whereby the same may be positioned over and in spaced parallel relation to said tank when in an inoperative position, a second swivel member interposed in said second named horizontal pipe, whereby the outer portion of said second named horizontal pipe may be rotated about a horizontal axis, and a discharge jet carried by the outer end of said second named 1pc. p In testimony whereof we afiix our signatures.
